This reconstruction of the Late Devonian estuarine lake at Waterloo Farm in South Africa captures the life history of an ancient lamprey species called Priscomyzon riniensis. Three individuals representing different ontogenetic stages take a shelter in the meadow of charophyte algae Octochara crassa. Clockwise from right: a yolk-sac-carrying hatchling tucked in the charophyte; a juvenile attached to the substrate in the foreground, and an adult looming over the other individuals and showing its feeding apparatus. In the background, a school of the coelacanth Serenichthys kowiensis swims by. Image credit: Kristen Tietjen.
